| Research Abstract |
Nowadays, artificially engineered proteins are utilized in various life science areas. In addition, engineered proteins are known to be one of promised candidates for next generation drugs. However, effective methods for rational design of artificial proteins have not been developed. Using comprehensive alanine insertion mutation analysis, we have revealed that regions of several subsequent amino acid residues in a protein, named as "Element", are responsible for the function and structure. In this work, we established a working hypothesis that those elements act as building blocks in the proteins, and verified it. In the result, by implanting the elements from a protein into another protein with a different function, we successfully modified the protein function as we wish. This success implies that the elements act as a kind of building-block to mediate a particular protein function, and will enable us to design an artificial protein rationally.
